rangement, but this bracket could be omitted or could be a fixed part of the lamp support, or could itself constitute the lamp support without departing from the present invention.

Instead of the studs or screws 12 being, as usual, rigidly secured to the inner end of the lamp casing, they are movably or adj ustably mounted within the lamp, as for instance by means of a disk or plate 15 with which they are rigid and which is located within the lamp casing against the inside face of the inner end wall 16 of the casing, with the studs 12 extending out through one or more suitable openings or slots 17 in the end wall 16. The studs may pass through holes in the stud plate 15 and be provided with heads 18 welded to the plate 15, or the studs may be rigidly secured to the plate in any other suitable manner. The stud plate 15 is loosely retained within the lamp casing adjacent to the inner end wall 16 of the casing and is preferably circular and of sufficiently smaller diameter than the internal diameter of this end of the casing to enable the stud plate to be turned in the lamp casing to the extent per mitted by the slots 17 through which the studs projec These slots are preferably of segmental circular shape concentric with the center of the end wall 16 and diametrically opposite to each other, and are long enough to permit the stud plate and the studs to be turned in the casing through an angle of ninety degrees. The studs, therefore, can be adjusted to project from the lamp casing in either a vertical diametrical plane as shown in Figs. 2, 3 and 7 or in a horizontal diametrical plane, as shown in Figs. 4 and 6. This adjustability of the lamp attaching studs 12 adapts them to be inserted either through holes arranged one above another in a vertical line in a bracket or support, or through holes in a horizontal line in the bracket. Each of the several brackets shown in the drawing is provided with one pair of holes 20 and 21 disposed in a vertical line, and also with a second pair of holes 22 and 23 disposed in a horizontal line and the studs can be adjusted so to be received by either pair of holes. But, as ordinarily constructed, the supporting brackets have only one pair of holes, which in some brackets are in a horizontal line and in other brackets are in a vertical line. However, the described adjustability of the studs 12 adapts the lamp to be secured in proper upright position on any such supports or brackets. lVhen the screw studs have been inserted through the holes in the brackets 11 and 14, and the nuts screwed up on the studs, the stud plate 15 will be drawn up against the inner side of the end wall 16 of the lamp casing while said end wall 16 will be drawn up against the bracket 11 or the holder 14 in case a separate holder 14 is used, all of the parts being thus clamped firmly and rigidly together by means of the screw studs 12 and their nuts 13, the lamp being thereby stationarily and rigidly secured in place.

In addition to the studs thus being adapted to be secured in either vertically or horizontally arranged holes in a bracket, or support, the nuts can be loosened and the lamp adjusted relatively to the bracket so as to secure the lamp in a correct, upright posi- 4 tion in the event that the bracket has not been accurately positioned on the vehicle or in case it may have been accidentally bent out of the intended position in which the stud holes are in either a horizontal or a vertical line. The attaching studs 12 being thus circularly adjustable on the lamp through an angle of substantially ninety degrees, enables the attaching studs to be readily adjusted to whatever position may be necessary to secure the lamp in upright position, whether the stud holesin the bracket be disposed in horizontal or vertical. line, or in any other intermediate position. Furthermore, since the attaching studsare not secured directly on the rear wall of the lamp casing but to the studplate 15, between which, and the bracket 11, the rear wall 16 of the lamp casing is clamped when the attaching nuts 13 are tightened, a strong and durable construction is provided even though the end wall of the lamp casing may be of relatively thin or light sheet metal. Such lamps are subject to severe vibration in the use of the automobiles on which they are mounted and this construction is much more durable than a construction in which the attaching studs arefixed directly on the end wall of the lamp casing.

I claim as my invention:

1. A lamp casing having an end wall provided with slots, a plate retained in said casing and having screw studs fixed thereto and projecting out through said slots, said stud plate being angularly adjustable in the lamp casing to permit the studs to project therefrom in different positions appropriate for engaging the studs in differently positioned holes in a support, and nuts cooperating with the threaded outer ends of said studs for securing said studs to a support and for also securing said stud plate stationarily in its difierent adjustments in the lamp casing.

2. The combination of a lamp having a casing with slots in its end wall, a stud plate rotatably adjustable in said lamp casing at the inner side of said end wall and having studs fixed thereto and extending therefrom out through said slots and adapted to be re movably inserted into holes in a support, and means cooperating with the outer ends of said studs to clamp said stud plate, end wall and support together.
